摘要：
The magnetic, structural and microstructural properties of bulk La1-xPrxMnO3+delta have been studied as a function of Pr doping. Magnetization versus temperature measurements show that La0.8Pr0.2MnO3+delta undergoes one magnetic transition, while La0.7Pr0.3MnO3+delta and La0.5Pr0.5MnO3+delta exhibit two magnetic transitions. X-ray diffraction and transmission electron microscopy studies indicate that all these compounds share an orthorhombic structure, which is derived from and also closely related to the ideal perovskite structure. Besides physical properties, the salient contrast between microstructures in these compounds is that there are high-density oriented microdomains in La0.8Pr0.2MnO3+delta, whereas La0.7Pr0.3MnO3+delta and La0.5Pr0.5MnO3+delta are free of these microstructural characteristics. A possible mechanism of domain formation is discussed.
